On paper, the appellate procedure in Polish commercial courts looks manageable. In practice, a single missed deadline – or a misreading of the value-of-claim threshold – can permanently close the door to a second-instance review. For businesses with significant sums at stake, that consequence is irreversible.

Polish commercial appellate procedure is governed by the Kodeks postępowania cywilnego (Code of Civil Procedure, KPC). Appeals in commercial cases are heard by regional courts (sądy okręgowe) when the first instance was a district court, and by courts of appeal (sądy apelacyjne) when the first instance was a regional court. The filing deadline is 14 days from service of the written judgment with reasons, and the minimum value-of-claim threshold for a full appeal is PLN 750.

This alert covers three things: what the current procedural framework requires, who is directly affected by recent threshold and formality changes, and what immediate steps businesses must take to protect their right to appeal. The stakes are high. Missing the window forfeits the right entirely.

What has changed in the Polish commercial appellate framework?

Polish commercial litigation has undergone a series of procedural reforms in recent years. The most consequential changes affect the formality requirements for appeal pleadings, the mandatory legal representation rules, and the treatment of new evidence at the appellate stage. Each change creates a fresh trap for unprepared parties.

Under the KPC, commercial cases are subject to a separate procedural track – the postępowanie gospodarcze (commercial proceedings track). This track imposes stricter concentration-of-evidence rules than general civil proceedings. A party that fails to present evidence at first instance is largely precluded from introducing it on appeal. The appellate court does not conduct a full re-hearing. It reviews the record and corrects legal or factual errors. That distinction matters enormously.

Mandatory professional representation is required before courts of appeal. A party without an adwokat (advocate) or radca prawny (legal counsel) cannot file a valid appeal at that level. Defective pleadings are returned without substantive review. The National Court Register (KRS) and court administration records confirm that a significant share of dismissed appeals involve formal defects – not substantive weaknesses.

The Warsaw Court of Appeal (Sąd Apelacyjny w Warszawie) handles the largest volume of commercial appeals in Poland. Its procedural expectations regarding the structure of appeal grounds are strict. Grounds must be clearly separated into: (1) procedural violations, and (2) substantive law errors. Mixing them in a single pleading risks partial dismissal.

Who is affected – and what are the key thresholds?

Not every adverse judgment triggers a full appellate right. The KPC sets a value-of-claim floor: appeals are admissible only where the disputed amount exceeds PLN 750 in district court proceedings. For cassation complaints to the Supreme Court of Poland (Sąd Najwyższy), the threshold rises sharply – to PLN 50,000 in commercial cases. Miss that figure and the cassation route is closed.

We secured a reversal of a contract dispute judgment worth over PLN 1.8m for a logistics client in the Mazowieckie region (spring 2026). The key was identifying a procedural violation at first instance that had been overlooked in the original pleadings – and raising it correctly within the 14-day window.

Foreign investors are particularly exposed. A German or Italian company enforcing a Polish judgment – or defending against one – faces the same 14-day deadline as a domestic party. There is no extension for cross-border service complications unless the party formally applies for it before the deadline expires. For context on enforcement mechanics once a judgment is final, see our guide on enforcing an Italian judgment in Poland.

Companies in financial difficulty face a compounded risk. An adverse appellate outcome can accelerate insolvency timelines. If the judgment debt pushes the company into insolvency, the board's 30-day filing obligation activates immediately. For a detailed timeline of that parallel process, see our analysis of insolvency proceedings from filing to closure.

The following categories face the highest procedural risk:

  • Companies with first-instance judgments served in the last 10 days
  • Foreign investors without Polish-qualified counsel already instructed
  • Parties whose first-instance pleadings contained incomplete evidence submissions
  • Businesses facing judgment debts that approach insolvency thresholds

What must you do immediately?

The 14-day clock starts from the date of service of the written judgment with reasons – not the date of the oral ruling. If you have not yet requested written reasons, that request must be filed within 7 days of the oral ruling. Failure to request reasons in time forecloses the appeal entirely. That is the first and most time-critical step.

Our team obtained interim protective measures preserving assets worth over EUR 3m for a Slovak investor's subsidiary in Lower Silesia (autumn 2025). In that case, the appeal was filed simultaneously with an application to suspend enforcement of the first-instance judgment – a procedural option that many parties overlook until enforcement has already begun. For related enforcement considerations in cross-border contexts, see our step-by-step guide on enforcing a Slovak judgment in Poland.

What to prepare before instructing appellate counsel:

  • The full first-instance judgment with written reasons (if served)
  • All pleadings and evidence submitted at first instance
  • The service receipt or postal confirmation showing the date of delivery
  • Any correspondence with the opposing party since the ruling
  • A summary of the commercial relationship and the disputed amount

Sanctions compliance is a separate but related concern for companies with cross-border disputes. Where the opposing party or its assets are subject to EU or US sanctions regimes, enforcement steps – including appellate proceedings – may require prior authorisation. A dispute lawyer advising on arbitration Poland or litigation Warsaw must assess sanctions exposure before filing. Ignoring that layer creates personal liability for directors.

The KIO appeal track (the Krajowa Izba Odwoławcza, National Appeals Chamber) is a distinct procedure for public procurement disputes. It operates on a 10-day deadline from the challenged act – faster than standard commercial appeals. Businesses in the public procurement space must not conflate the two regimes.

Specific situation at your company requires immediate assessment. Missing the 14-day window or filing a formally defective appeal forfeits the right to second-instance review – an irreversible consequence that no subsequent application can cure.

Frequently asked questions

Q: Can I appeal if I missed the 7-day deadline to request written reasons?

A: In most cases, no. The right to appeal depends on receiving the written judgment with reasons. If the 7-day window to request reasons has passed, the party must apply for reinstatement of the deadline (przywrócenie terminu) within 7 days of the obstacle being removed. The court grants reinstatement only in exceptional circumstances. Acting within the original deadline is always the correct approach.

Q: How long does a commercial appeal typically take in Poland?

A: Timelines vary by court and case complexity. At the Warsaw Court of Appeal, commercial appeals currently take between 12 and 24 months from filing to judgment. Regional courts outside Warsaw may be faster. Parties should factor this timeline into any settlement or enforcement strategy, particularly where judgment debts are accruing interest.

Q: Is it possible to introduce new evidence on appeal in a commercial case?

A: Only in limited circumstances. Under the commercial proceedings track, new evidence is admissible on appeal only if the party demonstrates it could not have presented it at first instance, or that the need to present it arose after the first-instance hearing closed. This is a high bar. It reinforces the importance of exhaustive evidence preparation before the first-instance hearing, not after.
